Specifically, the enterprise user fills in enterprise information including an enterprise name, an enterprise type, an industry to which the enterprise belongs, enterprise certificate information, enterprise contacts, a contact phone and the like, and submits an identification code prefix application request. The industrial internet identity analysis platform audits the enterprise users according to the enterprise information, for example, the enterprise users can be audited through manual auditing and by an administrator through the industrial internet identity analysis platform, and the identity prefix information is distributed or sent to the enterprise users after the auditing is passed. Meanwhile, enterprise users can set enterprise nodes according to each production link of the product, information of each production link is filled in corresponding enterprise nodes, after a certain production link of the product is completed, an identification code for uniquely identifying the certain production link of the product and corresponding production link information are synchronously sent to the industrial internet identification analysis platform by the enterprise nodes, and then the identification code and the corresponding production link information are sent to the block chain platform, the recursive node platform and the national top node platform by the industrial internet identification analysis platform. Preferably, the industrial internet identity resolution platform can periodically (for example, one week and one month, and the time can be set) synchronize the identification code and the production link information with the blockchain platform, the recursive node platform and the national top node platform.
In this embodiment, the identification code is composed of identification prefix information and identification suffix information, the identification prefix information can uniquely identify one product, the identification codes belonging to different production links of the same product have the same identification prefix information, and the identification prefix information includes a country code, a secondary node code and an enterprise node code. Preferably, the country code is 2 bits, the secondary node code is 3 bits, and the enterprise node code is 10 bits. For example, 88.185.XXXXXXXXXX represents the business applying for an identification code prefix in the secondary nodes in the west and the west. The identification suffix information can be set by the enterprise user in a self-defined way, for example, the identification suffix information can be set according to the manufacturer information corresponding to each production link.
In this embodiment, the identification codes may be divided into a product overview identification code and a product production link identification code according to different production links, the product overview identification code is an identification code of a product overview link, suffix information of the product overview identification code may be set to a certain fixed code or may be null, and the product overview identification code and the identification prefix information are preferably the same. The identification codes of other links except the product summary link are the identification codes of the product production link.
Optionally, the storing the identification code and the corresponding production link information into the block corresponding to the identification prefix information may specifically include:
judging whether the identification code is a product summary identification code;
if so, creating a block, wherein the block head of the block comprises identification prefix information, a root hash value and a first timestamp, and the block body of the block comprises production link information corresponding to the product summary identification code;
if not, the identification code is judged to be a product production link identification code, a sub-block corresponding to the product production link identification code is created in the block body, the block head of the sub-block comprises the product production link identification code, a sub-block chain version number and a second timestamp, and the block body of the sub-block comprises production link information corresponding to the product production link identification code.
In this embodiment, the identification suffix information of the product summary identification code is preferably null, that is, the product summary identification code is the same as the identification prefix information, and when the blockchain platform receives the product summary identification code sent by the industrial internet identification resolution platform, the blockchain platform creates a corresponding block, where a blockchain header may include a blockchain version number, a root hash value, a last blockchain hash value, identification prefix information, a timestamp, and a random number. The block body can contain the detailed information of the production link, namely product summary information, and can also comprise: identification prefix information, identification code information of all product production links under the identification prefix information, sub-block index information and the like. If the block chain platform receives a product summary identification code sent by the industrial internet identification analysis platform, a sub-block corresponding to a product production link identification code is created in the block, wherein each piece of production link information is stored in one of the sub-blocks, each sub-block key is a sub-block chain version number + a timestamp + the product production link identification code, and a digital signature is the production link data signature information. For example, the identification code corresponding to each production link of a target product and the contents of the enterprise node and the block may be as shown in table 1, wherein the enterprise node code is preferably 10 bits.

In order to facilitate tracing of subsequent product information, the block chain platform can send the public key corresponding to each identification code and the enterprise digital signature information, or the sub-block key and the production link digital signature information to the recursive node platform.
In this embodiment, when a user or another third party wants to view product information, an identification code analysis request may be sent to the recursive node platform by scanning an identification carrier on a target product through the user equipment. The recursive node platform analyzes the identification code in the identification code analysis request, sends an information acquisition request carrying the identification code to the block chain platform, returns corresponding production link information to the recursive node platform after receiving the request, and feeds the production link information back to the user equipment so as to realize the tracing of the product information.
In a specific example, the tracing process of the product information includes the following steps:

And the recursive node platform acquires detailed information corresponding to the production link from the block chain platform and feeds the detailed information back to the user.
(3) When the recursive node platform analyzes that the product production link identification code is queried by the user, the recursive node platform sends an information acquisition request carrying the product production link identification code, a sub-block key (sub-block key is a sub-block version number + a second timestamp + the product production link identification code) and production link digital signature information to the block chain platform, the block chain platform verifies the sub-block key and the production link digital signature information, and after the verification is passed, the production link information corresponding to the product production link identification code is acquired and fed back to the recursive node platform, and the recursive node platform feeds back the corresponding production link information to the user.
(4) When the user or other third party wants to continuously check the product summary information, the product summary identification code can be input to the recursive node platform, and the recursive node platform acquires the detailed information of the corresponding production link from the block chain platform and feeds the detailed information back to the user.
(5) When the recursive node platform analyzes that the identification code queried by the user is not the product summary identification code or the product production link identification code, the recursive node platform feeds back the information to the user.
According to the method for storing the product information, provided by the embodiment of the invention, the identification code for uniquely identifying a certain production link of the target product and the corresponding production link information sent by the industrial internet identification analysis platform are received, the identification prefix information of the identification code is obtained, and the identification code and the corresponding production link information are stored in the block corresponding to the identification prefix information, so that the authenticity of product data is ensured.
